Purpose

To help develop Conservation Significance Assessment Maps. The assessment assigns remnant vegetation into one of four significance categories, based on area of remnant vegetation and percent canopy cover:1. Core Habitat2. Support for Core habitat3. Urban Remnant Trees (Critically Endangered Communities)4. Other Remnant Vegetation.See NPWS (2002)

Lineage

Dataset derived through Aerial Photographic Interpretation. Aerial Photos at 1:16000, flown between 25/11/1997 and 11/03/1998 where interpreted to delineate the current extent and condition of remnant vegetation (>0.5ha patch size). 4000 polygons were visited to extrapolate vegetative patterns across the landscape based on the dominant canopy species and other attributes. The delineation of remnants was scanned and rectified into GIS database format. Polygons were assigned vegetation community codes based on modelled relationships between field survey sites and environmental variables.

Explanation

All attributes except Community_id where coded to polygons during the interpretation process. During this process, 4000 sample points were visited with the attributes in these polygons noted. These points formed a basis from which to extrapolate features across the study area using patterns observable from aerial photographs. Polygons assigned an A class polygon_code had all their attributes recorded. The other non-A class polygons where assigned partial codes. B class polygons where assigned species codes whereas only a portion of the Tx class polygons where assigned this attribute.Community_id was identified for each polygon using the relationship between the position and characteristics of each polygon to the modelled vegetation community map. Communities were directly attributed to those API polygons wholly within the modelled area of a community. Those not wholly within the modelled area of a community were identified using a rule set relating polygon characteristics to the modelled vegetation community. Further explanation is available in the report titled Native Vegetation of the Cumberland Plain, Western Sydney.
